FEATURES - Meets industry safety standards - Strobe-light and weld-flash immunity - 200' (60 m) maximum operating range - Less than 35-ms response time - Available in standard 115-V AC or optional 24-V DC version - Diagnostic and signal-strength indicators - Multiple sides can be safeguarded with the use of mirrors - No electrical connection between the transmitter and receiver This single-beam unit is a long-range single-beam safety device designed specifically for perimeter or area safeguarding. It can be used for whole-body detection and must not be used for point-of-operation safeguarding. It can be used for safeguarding hazardous areas around machines and processes such as press feeding equipment, robotic work cells, automatic machinery work envelopes, assembly lines, conveyors, palletizers, stackers and plastic-injection molding machines. The single-beam unit consists of a transmitter and receiver. They are housed in separate cast-aluminum enclosures and have their own power supplies. This means no interconnecting cables or separate control enclosure is required. They are an infrared presence-sensing device which transmits and receives a single beam of light. Interruption of this single infrared beam sends a stop signal to the machine's control. This signal is designed to stop hazardous machine motion or prevent the initiation of machine motion. These units have a diverse-redundant microprocessor which provides control-reliable operation. If there is an internal malfunction, a stop signal is generated. |

The transmitter sends a coded infrared light to the receiver. This feature minimizes interference from other single-beam units in close proximity or from other light sources. Mounted on the receiver are four separate visible indicators which provide information on the status of the unit. These indicators include system clear, blocked, interlocked status, and signal strength. The single-beam safety device can be connected to a machine control system with an optional quick-disconnect cable kit or with user-supplied cable. At least two beams are required for each safeguarded plane. This can be accomplished with two separate units or with mirrors. Mirrors increase the coverage of the safeguarded area. Floor stands and mounting accessories are available for the single-beam device. For special applications, please consult the factory. |
